Ntchito ya minofu minofu mitundu kapangidwe

Thupi la nyama zonse, kuphatikizapo anthu, wapangidwa amitundu inayi minofu: zaminyewa, mantha, connective ndi akulu. Pa yotsirizira ayankhidwa m'nkhaniyi.

Zosiyanasiyana minofu minofu

N'zochititsa mitundu itatu:

• striated;
• kusalaza;
• mtima.

Nchito ya minofu minofu ya mitundu yosiyanasiyana amasiyana pang'ono. Ndipo kapangidwe kwambiri.

ndi kumene minofu minofu mu thupi la munthu?

Minofu minofu ya mitundu yosiyanasiyana zatenga malo osiyana mu thupi la nyama ndi anthu. Choncho, kunja kwa minofu mtima, monga dzina lake likunenera, inamangidwa mtima.

Kuchokera striated minofu chigoba anapanga minofu minofu.

minofu yosalala mzere mkati M'mimbamo, amene ayenera kuchepetsedwa. Mwachitsanzo, matumbo, chikhodzodzo, chiberekero, m'mimba, etc.

minofu Kapangidwe ka mitundu yosiyanasiyana zimasiyanasiyana. Pa nkhani yake mwatsatanetsatane lotsatira.

Kodi minofu minofu?

Amakhala ndi maselo lalikulu-kakulidwe - ena a minofu. Iwo amatchedwanso CHIKWANGWANI. Minofu maselo adzalandira Mipikisano pachimake ndipo ambiri mitochondria - organelles udindo kupanga mphamvu.

Komanso, kapangidwe ka minofu ya zimakhala anthu ndi nyama kumafuna pamaso pa pang'ono intercellular mankhwala okhala kolajeni, amene amapereka elasticity minofu.

Tiyeni tione kapangidwe ndi ntchito ya minofu minofu ya mitundu yosiyanasiyana payokha.

Kapangidwe ndi udindo wa minofu yosalala minofu

nsalu uno umalamulidwa ndi mantha dongosolo autonomic. Chotero, munthu Sakuchepetserani minofu bwino anamanga kwa nsalu yosalala.

Iwo anapanga kuchokera mesenchyme lapansi. Ndi mtundu wa embryonic connective minofu.

Kumachepetsa minofu imeneyi zambiri layamba mofulumira kuposa striated.

Sinkhasinkha nsalu inamangidwa wa mawonekedwe myocytes fusiform ndi malekezero zisonga. Kutalika kwa maselo amenewa zingakhale za micrometers 100 mpaka 500, ndi makulidwe - pafupifupi 10 micrometers. Maselo a minofu ndi mononuclear. phata ili pakati myocyte lapansi. Komanso bwino anayamba organelles monga mitochondria ndi EPS agranular. Komanso mu mnofu yosalala maselo minofu ndi ambiri inclusions glycogen, zomwe zimapanga nkhokwe ya zakudya.

The mfundo amapereka kuchepetsa minofu minofu ya mitundu, ndi myofilaments. Iwo akhoza inamangidwa mapulotini awiri contractile akitini ndi myosin. Awiri myofilaments kuti zigwirizana myosin, ndi 17 nanometers, ndi anthu amene anamanga wa akitini - 7 nanometers. Palinso myofilaments wapakatikati amene awiri ndi 10 nanometers. Lathu kotenga myofibrils.

Kapangidwe ka mtundu wa minofu minofu mulinso extracellular masanjidwewo ya kolajeni, amene amathandiza mgwirizano pakati myocytes payekha.

Nchito ya minofu minofu ya mtundu uwu:

• Sphincter. Kodi a zimakhala yosalala minofu anakonza mu zozungulira malamulo zili kusintha thupi wina kapena kuchokera mbali ina ya thupi lina.
• Kuthawa. Iwo kwagona kuti minofu yosalala kuphedza manungo excrete mankhwala zinyalala, komanso nawo ndondomeko za pobereka.
• Kujambula lumen mtima.
• Mapangidwe zida za ligamentous. Uyamiko kwa Iye, ziwalo zambiri, monga impso, ikuchitikira ku malo.

Tsopano tiyeni tiyang'ane pa mawonekedwe a minofu minofu.

Striated

Iwo amatsatila mantha dongosolo somatic. Choncho, munthu akhoza bwino malangizo mtundu wa minofu. Kuchokera striated chigoba minofu minofu aumbike.

minofu tichipeza ulusi. Awa ndi maselo omwe kuchuluka kwa mitima oyenerera kuyandikira kwa Kakhungu plasma. Komanso, muli yambiri inclusions glycogen. Bwino anayamba organelles monga mitochondria. Ali pafupi ndi maselo contractile wa zinthuzo. organelles zina zonse zili pafupi mtima ndi bwino anakamba.

Nyumba kudzera amene mtanda milozo nsalu yafupika, ndi myofibrils. awiri awo ndi pakati ndi awiri micrometers. Myofibrils zatenga kwambiri kwa chipinda ndipo anaika mu malo ake. Lathu kotenga myofibrils. Iwo wapangidwa kuwala ndi mbale mdima, alternating, amene amalenga mtanda "milozo" nsalu.

Nchito ya minofu minofu ya mtundu uwu:

• Kupereka thupi akusuntha mu mlengalenga.
• Udindo kayendedwe ka ziwalo wachibale wina ndi mzake.
• Luso kukhalabe kaimidwe thupi.
• Nawo lamulo la kutentha: yafupika minofu yogwira, ndi apamwamba kutentha. Pamene kuzizira minofu striated akhoza kuyamba kutenga involuntarily. Nchifukwa chake kunthunthumira za thupi.
• Kutumikira ntchito ndi zoteteza. Zimenezi ndi zoona makamaka kwa minofu m'mimba, amene amateteza ziwalo zambiri mkati zisaonongeke.
• Zinthu monga zofikira wa madzi ndi mchere.

Mtima minofu minofu

nsalu Izi zikufanana onse striated, ndipo yosalala. Komanso osalala, izo ndi Lamulo mantha dongosolo autonomic. Komabe, m'mbuyo monga mwachangu monga striated.

Amakhala ndi maselo otchedwa cardiomyocytes.

Nchito ya minofu minofu ya mtundu uwu:

• Ndi chimodzi chokha: kuonetsetsa kayendedwe ka magazi m'thupi.
